Less isn't always more! After months of making headlines for wearing very little (or nothing at all), Miley Cyrus covered up in a floor-length gown at the "Galaxy"-themed 30th Annual Night of Stars event on Tuesday, Oct. 22 -- and the results were stunning.

Walking the red carpet at New York City hotspot Cipriani Wall Street, the 20-year-old "Wrecking Ball" singer turned heads in a glittering green Marc Jacobs frock, which she paired with Saint Laurent shoes and Lorraine Schwartz jewels. Compared with some of the former Disney star's more recent ensembles, the dress was demure -- but only from the front.

The sequined gown showed plenty of skin from behind, scooping low on the fashion-conscious diva's back. Green eyeshadow and a slicked-back 'do completed the glam look.

An onlooker tells Us Weekly that Cyrus -- who was at the event to present the Superstar Award to Marc Jacobs -- was "smiling a lot" on the red carpet. She declined to do any interviews, but she did turn around and flash a big grin when asked by Us whether she was ready to fall in love again. (The Hannah Montana alum split from fiance Liam Hemsworth earlier this past summer.)

"I'm just letting that chapter kind of close, and just looking forward to that new one," the Bangerz artist told Ellen DeGeneres recently of their breakup. "I want to be really clear and determined with everything that I'm doing in my life right now, and I have been."

She continued: "I keep saying I'm the happiest I've ever been, and that's not even a dig. That's just me, because I really am genuinely happy finally with myself. I think sometimes it takes you separating yourself from someone else to really be happy with who you are. I've never been able to just be alone -- and I'm obsessed with being alone and hearing my thoughts."
